Question

female gametophyte in full detales

Answer 1

Answer

• The diploid megaspore cell undergo meiosis.

• It tends to form four haploid megaspore.

• These four megaspore are arranged in a linear tetrad.

• Out of the four megaspore, the upper three megaspores are at the micropylar end.

• They tend to degenerate and disappear.

• The remaining one of the tetrad at the chalazal end becomes functional megaspore.

• It enlarges and develops in to female gametophyte or embryo sac.

• The functional megaspore is the first cell of the female gametophyte.
